| 摘 要： | 用显式有限差分法对超燃发动机（Ｓｃｒａｍｊｅｔ）的燃烧室内流场进行了数值模拟。计算中采用了ＭａｃＣｏｒｍａｃｋ两步显格式、Ｂａｌｄｗｉｎ－Ｌｏｍａｘ代数湍流模型以及两方程、四组分的化学反应模型。为了解决源项的刚性问题，运用点隐式方法对它作了隐式处理。

| Abstract: | Numerical simulations of chemically reacting flows in scramjet combustor have beencompleted, MacCortnack's two step explicit scheme and Baldwin-Lomax algebric turbulence model areused. The chemistry model is a finite rate two equation model, A point-implicit method is used to treatthe source term. |
